"We told swimmers that selection qualification for the World Championships would be tough and the reasons why.

"Standards across Paralympic sport are going through the roof and we expect Rio to be challenging. It is important to create a challenging environment for athletes where they have to come to trials and perform well."

Firth delighted with world record

Among those on the team are London Paralympic champions Ellie Simmonds and Ollie Hynd, as well as veterans Sascha Kindred and James Crisp.

Bethany Firth and Hannah Russell, who both set world records at the weekend's trials at the Tollcross International Swimming Centre, which will also host the Worlds from 13-19 July, are also included.

Simmonds, who achieved qualifying standards in the 200m medley and 400m freestyle in her S6 category, wants the British public to come out and support the team again in Glasgow this summer.

"The home crowd really lifted us in London and hopefully this year we will have big crowds giving us that extra boost again and we can show everyone what we are made of," the 20-year-old told BBC Sport.

"It's great we have had world records at the trials so we know it is a fast pool and that gives us a lot of confidence and we will be at our best to race there in July."
